摘　　要：RNAi(RNA interfering)是由靶基因同源的双链RNA引发的在动植物中普遍存在的序列特异性转录后基因沉默.最早在植物体中发现,现已成为后基因组时代的重要研究手段.对RNAi在植物功能基因组、生长发育、抗病毒、品质改良方面的最新研究进行了综述,展望了今后的发展前景.RNAi （RNA interfering） is initiated by homology double strand RNA of target gene, and is the sequence specificity post-transcriptional gene silence that universal existence in the zoology and botany. It was discovered earliest in the botany, and was important research method in the Post-genomic Era. The new developments of RNAi at the botany functional genomic, growth and development, resistance, the quality improvement aspect are reviewed. At last, the challenge and prospect of RNAi are discussed.
